LYNDAN C. PALMER, OF BUFFALO, NEW YORK, ASSIGNOR T0 15. N. BURT COMPANY, LIMITED, OF BUFFALO, NEW YORK, A CORPORATION OF ONTARIO, CANADA.

BOX-MAKING MACHINE.

To all whom it may concern Be it known that I, LYNDAN C. PALMER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Box-Making Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to box-making machinery, and more particularly to mechanism for pressing or squeezing adhesively attached elements of a box in order to more securely retain them in position, including devices for supporting and feeding boxes successively into and out of position for the application of the pressure.

()ne of the objects of the invention is the provision of an eflicient mechanism for successively feeding adhesively attached box elements and pressing said elements together. I

Another object of the invention is the provision of simple mechanism whereby the movable element of the press may be moved into and out of the path of the boxes.

Another object of the invention is the provision of practical means for applying the pressure on the inside of the box.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope'of the appli cation of which will be indicated in the following claims.

In the accon'ipanying drawings, wherein is shown one of the various possible eiubodi ments of this invention: Figure 1 represents the mechanism in elevation when connected to a box making machine; Fig. 2 is atransverse section through Fig. 1 on the line w-y; Fig. 3 represents the pressing device elevation partly in section; Fig. 4c is a lan of the press heads; Fig. 5 is a cross sec ion on line A..-B; Fig. 6 is a perspective view of a preferred form of box. 7

This invention is preferably intended $0 press the shouldered boxes as they are delivered from the machine shown in application filed January 16, 1911, Serial No. 602,862, improvements in box machines, and

Specification of Letters Patent.

is preferably set up as a part of said machine, its operating mechanism being driven by a suitable connection with the operating mechanism of said machine.

Referring now more specifically to the drawings, the numerals 1 indicate parallel vertically disposed guide bars provided with horizontally disposed shoulders 01 tracks 2 adapted to support the boxes as they are delivered from the carriage of the machine set forth in the above-entitled application. The boxes produced by the aforesaid ma chine comprise a head 3, a flange 4 surrounding the head, and. a collar or neck 5 which fits or telescopes within the box, being adhesively attached to the inner wall of the flange. As these boxes are delivered from the machine above referred to it may happen that the collar will not be uniformly secured throughout its extent to the flange, and it is therefore desirable to press or squeeze the collar and flange together, in order to uniformly attach the same. To this end, after the boxes are delivered from the carriage of the aforesaid machine they are fed between the plates 1, being supported by their shoulders 6 on the tracks 2, the openings of the boxes being disposed downwardly. The elements 1 and 2 may be merely continuations of the guideway formed by the channel bar of the aforesaid application. The pressing elements of the present application are preferably designed to act upon the inner lateral walls of the boxes while they are supported between the plates 1, said plates thereby serving as pressing platens for opposite walls of the box, between which and the press heads the collar and flange are squeezed for the purpose aforesaid.

Preferably the channel bar denominated 384C in the aforesaid application is elongated and its outer portion forms What may be termed the press end of the channel bar, corresponding to the plates 1. Depending from and supported by the outer portion of the elements 1 is a U-shapcd bracket 7 provided with a bearing box 8 in which is journaled a horizontal rock shaft 5). The shaft 9 is also supported in a bearing bracket 10, and its inner end adjacent the frame of the machine is provided with an arm ll carrying an anti-friction roller 12 in position to be operated by a cam 13 on a rotary shaft 1 preferably identical with one of the continuously driven shafts of the aforesaid machine.

The bottom portion-15 of the bracket 7 is provided with an opening 16, and a fixed vertical guide or sleeve 17 is suitably secured to the cross piece 15 in line with the opening 16, as by nieans of the nut 18. The periph ed to be moved into and out of, the box and also in a direction'to press against the'lateral walls of the box on the interior of said box. Inasmuch as the box has a continuous wall, and in the present case four walls disposed at right angles to each other, four press heads corresponding to the head 21 are employed. The heads 21 have flat laterally disposed pressing faces adapted to contact the walls of the box when properly operated, and each head is provided with a depending supporting arm 22 and is guided in its movements toward and from working position relatively to the box, preferably by a retaining member or collar 23 surrounding the fixed guide 17 and movable up and down on said guide, each arm 22 being pivotally connecte to the retaining member, as at 24. In the present embodiment a spring 25 surrounds the member'17 between the cross piece 15 and the retaining member, and this spring is of such a character as to move or elevate the press heads into working position opposite. the portion of the walls of the box tobe operated upon, and preferably will elevate the heads to such ah extent that when moved laterally said heads will contact with the inuer'walls of the box above the shoulder 6. p

The heads 21 being pivotally connected to the retaining member, are further guided in their upward movement by the rod 19, to which each head is connected, respectively, by links 26 pivotally joined to each head and to the upper end of the rod. 19. The outer portion of the rockshaft 9 is provided with an arm 27 pivotally joined to a connecting rod 28, in turn pivotally connected to a block 29 which may be adjustably clamped at different points on the rod 19. By this construction the rotation of the shaft 14 will cause the cam 13 through the connections described to raise the rod'19, whereupon the spring 25 will cause the heads 21- to be elevated with the rod 19, and the press headsv being positioned so as to cause the upward movement to cease substantially opposite the part ofthe box to be pressed. The heads 21 having been elevated to working position and their rise having been terminated by the stops 30, a furtherupward movement of the rod19 is effected by the cam 13, where upon the heads 21 are moved at an angle to their upward movement and caused to press against the lateral walls of the box, thus squeezing the same between the press heads and the platens 1. The pressure having been effected, the cam 13 permits the rod 19 to descend, its descent being assisted by a spring 31 encircling the rod 19 and interposed between the nut 18 and the clamp block 29, the spring '31 being of sufficient strength'to cause the descent of the heads 21 against the resistance of the spring 25.

The pressing faces of the heads 21 are substantially the same in length as the walls of the box against which they operate. It will be observed that the heads 21 are so disposed as to move simultaneously into and out of working position, and also that their.

pressing movements are accomplished simultaneously, and that they move toward and from each other when moving into and out of pressing position. The heads 21 are so disposed when in lower position as to readily escape the edges of the box, and while any suitable means may be employed to limit their inner position, advantage is taken of the fact that a plurality of heads is employed, and't-heir inner movement is limited I by bringing the heads into contact with each other. The heads are disposed in the shape of a rectangle and the ends of each head are beveled, as at 32, so that each head forms, with an adjacent head, a miter joint, so to speak. Thus when the heads descend the ends of each head contact with adjacent opposite heads, restricting further inward movement. The rectangular shape of the guide 17 prevents any substantial rotary movement of the heads relative to a symmetrical axis, thus preserving the 'alinement of the several heads with the walls of the boxes, once that alinement has been determined.

The mechanism'for feeding the boxes successively into pressing position is similar to the mechanism for removing the boxes from the carriage, as'described in the prior application above referred to. In the illustration Figs. 1 and 2, a portion of the mechanism corresponding to that of the aforesaid application is shown. The numeral 33 represents a continuously driven shaft which, through chain 34, continuously rotates shaft 14 on which cam 13 is mounted. The crank 13o wheel 35 is intermittently driven from shaft '33, by means of mutilated gears and reciprosucceeding box into position immediately over the pressing mechanism.

It Wlll now be seen that the above-described construction provides a mechanism capable of efiiciently accomplishing, among others, the objects hereinbefore stated.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
